The WITCH Model. Structure, Baseline, Solutions

摘要: Summary WITCH – World Induced Technical Change Hybrid is a regionally disaggregated hard-link hybrid global model with neoclassical optimal growth structure (top-down) and detailed energy input component (bottom-up). The endogenously accounts for technological change, both through learning curves that affect the prices of new vintages capital R&D investments. features main economic environmental policies in each world region as outcome dynamic game. belongs to class Integrated Assessment Models it possesses climate module feeds changes back into economy. Although model’s are discussed elsewhere (Bosetti et al., 2006), here we provide more thorough discussion baseline projections, describe greater detail. We report information on evolution demand, technology CO2 emissions. also explain procedure used calibrate parameters. This therefore meant effective support those who intending use or interpret its results.
